Kryptonite Ransomware – Delivery Ways

Kryptonite ransomware could be delivered in more than one way. However, the way that is the most widespread is through a payload dropper. That is a file which initiates the malicious script for the ransomware. Malware samples have been spotted by researchers and you can view one of them, which was sent for analysis on the VirusTotal service, from down here:

Kryptonite ransomware could be using other ways to deliver the payload file, like social media and sites for file-sharing. Freeware applications located on the Web could be promoted as being useful, but could also hide the malicious script for the virus. Before opening any files after you have downloaded them, you should first scan them with a security tool. Especially if they come from suspicious places, such as emails or links. Also, don’t forget to check the size and signatures of such files for anything that seems out of place. You should read the ransomware prevention tips provided in the forum.

Kryptonite Ransomware – Detailed Analysis

The Kryptonite ransomware is a cryptovirus, which has been disguised as a Command Prompt variant of the famous Snake game as shown in the picture:

When the Kryptonite ransomware encrypts your files you will notice a file that is a ransom note containing instructions on how you might get your files recovered.

Kryptonite could be set to make new registry entries in the Windows Registry to achieve a higher level of persistence. Those entries are usually designed in a way that will start the virus automatically with every launch of the Windows Operating System, like in the example down below:

→“HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run”

The ransom note is in a file called “Ransom Note.txt“. Besides the text file a copy of the note with a more concise message is displayed as a picture, too:

Below you can read what the text on that image is:

ATTENTION All your files, images, vidoes and databases have been encrypted with an RSA-2048 private and unique key generated for this computer stored on a secret server. Original files have been over written, recovery tools will not help. Don’t worry!! We could help you restore your files but it will cost you 500$ Follow the instructions on ‘Ransome Note.txt’ file on your desktop. After payment is confirmed, use the Decryptor program to restore yor files. If you care about your files, DO NOT TRY TO GET RID OF THIS PROGRAM!! Any actions to do so will result in decryption key being destroyed, and you will loose your files forever!

Three variants of the ransom note exist. Down here you can preview them:

The ransom sum that is demanded as payment for allegedly restoring your files is currently 500 US dollars. No matter what sum of money is asked from you, you shouldn’t in any case consider paying the cybercriminals. Paying these crooks can motivate them to continue committing similar crimes as extorting people online.

Kryptonite Ransomware – Encryption Process

No official list exists, with file extensions that the Kryptonite ransomware seeks to encrypt. This article will be duly updated if such a list is discovered. However, all files which get encrypted do not have their extensions changed. Alas the files are still scrambled and unusable.

Kryptonite is highly likely to erase the Shadow Volume Copies from the Windows Operating System by executing the following command:

→vssadmin.exe delete shadows /all /Quiet

In case the above-stated command is executed in the Command Prompt of the Windows OS, that will make the encryption process more effective, as one of the ways for file recovery will be gone. That command’s execution is not hard as the virus poses as Command Prompt variant of the game “Snaked” as mentioned before. That means that the virus already has access and uses CMD. Keep reading to find out what methods you can try out to potentially restore some of your files.

4. Try to Restore files encrypted by Kryptonite

Try to Restore Files Encrypted by Kryptonite

Ransomware infections and Kryptonite aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.

Method 2: Trying Kaspersky and EmsiSoft’s decryptors.If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:

Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.

Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
